Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.11 g/mol gives Furan-2,3,4,5-tetracarbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Furan-2,3,4,5-tetracarbaldehyde (CAS 37812-28-5) is a high-purity analytical reference standard with the molecular formula C8H4O5 and a molecular weight of 180.11 g/mol.
Furan-2,3,4,5-tetracarbaldehyde (C8H4O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
